To enable these remaining troops to cross in safety was the last, and by no means the easiest task of the day. For the Carduchians were still behind, only waiting for the moment when they could most effectively fall upon them. Until the greater part of the men were in the water, they did not venture down from their mountains, but as soon as they saw that comparatively few of them were left on the bank, they dashed forward, as if they wished to teach the Hellenes the truth of the proverb that the last man is bitten by the dog. But Xenophon was prepared to receive them. Before taking any notice, he allowed them to come almost within close quarters. Their arrows were even whirring already through the air when he gave a signal with the trumpet. Then the hoplites turned suddenly, and charged with rapid step, shouting the Hellene war-cry. The Carduchians fled back into shelter as fast as they could, for they knew well that except in their own mountains they were no match for the Hellene troops. Once more the trumpet sounded, and the Carduchians fled yet faster than before, but Xenophon had previously given secret instructions to the men, that when they heard the second signal for attack, instead of obeying it they should turn back and hasten across the river as quickly as possible. This they did, and thus the crossing of the Kentrites, which in the beginning had seemed almost impossible, was accomplished by the Hellenes with little or no loss. XXXIII THE SATRAP TIRIBAZUS The Hellenes were now in Armenia. In this country there were no dangerous mountains, such as those they had just left, but here they had to contend against difficulties of another kind. The greater part of the country was 5,000 feet above the sea level, and in consequence of this, the winters were very long and cold, and the summers very short. In June the corn began to sprout. In September the harvest was gathered, and then the winter set in. It was now December, and the Hellenes were soon to experience the intense cold of an Armenian winter. After crossing the Kentrites, they marched for a distance of a hundred and twenty miles over level country, without encountering any enemy. These marches occupied six days, and it mostly chanced that in the evening they found themselves near villages where they could shelter for the night. On the seventh day there came to meet them a troop of horsemen, commanded by the satrap Tiribazus, who stood high in the favour of the Great King, and enjoyed the privilege, when he was at court, of helping the sovereign to mount on horseback. He rode forward towards the Hellene army, and demanded speech of the generals, announcing that he was desirous of entering into a treaty with them. They were to promise that they would neither burn the villages nor do violence to the inhabitants, but they were at liberty to take any provisions that they might require; and he, for his part, would undertake not to molest them in any way.
